Abstract
The utility model belongs to the field of a pipeline, and aims at providing a novel pipeline elbow with an inner pipe inside a metal elbow body for solving the problems that an anticorrosive material on the inner wall of the existing pipeline elbow is likely to drop and the elbow is likely to corrode. The pipeline elbow comprises a metal arc elbow body, wherein a flange is respectively welded on two ends of the metal arc elbow body, the inner diameter of each flange which is respectively welded on two ends of the elbow body is different, an inner pipe is arranged in the metal arc elbow body, two end parts of the inner pipe are respectively a flanged structure, and a steel wire supporting ring is arranged inside the flange; the inner pipe is made of polytetrafluoroethylene material; a netted anticorrosive layer is arranged in the inner pipe; an anti-abrasion cover is arranged outside the metal arc elbow body. The pipeline elbow is simple in structure; the polytetrafluoroethylene inner pipe is arranged in the metal arc elbow body, so that the corrosion of medium on the metal arc elbow body can be prevented, and the service life of the metal arc elbow body is greatly prolonged; moreover, when the inner pipe is damaged, only the inner pipe needs to be replaced, and the unnecessary waste of the material can be reduced.
Description
Technical field
The utility model belongs to pipeline field, relates in particular to a kind of channel bend.
Background technique
In the foundation engineerings such as chemical industry, building, plumbing, oil, hot-water heating, freezing, fire-fighting, electric power, often to use various pipelines, and pipeline is all generally straight, this just needs a kind of channel bend, the channel bend using is at present all generally rigidity elbow, at the inner-wall spraying anti-corrosion material of rigidity elbow, this elbow is because the anti-corrosion material of inwall is that spraying method is attached to inner-walls of duct, and its time length easily comes off, cause the corrosion of medium to elbow, reduce the working life of elbow.
Model utility content
For existing channel bend inner wall anti-corrosive material, easily come off, cause elbow perishable, the utility model provides the novel pipeline elbow that is provided with inner tube in a kind of metal bends body.
The technical solution of the utility model is as follows:
A kind of channel bend, comprise metal arc elbow body, in described metal arc elbow body, be provided with inner tube, the two ends of described metal arc elbow body are welded with flange plate, inner wall even distribution at flange plate has projection or C type groove, the flange plate internal diameter of described two ends welding varies in size, and the two end part of inner tube are turnup structure, and flange inside is provided with steel wire support ring, metal arc elbow body outside is provided with an anti-abrasion cover, anti-abrasion cover comprises upper cover and lower cover, and upper cover and lower cover engaging, in metal arc elbow body, be provided with an one-way valve, one-way valve is eccentric-butterfly-valve, on metal arc elbow body, be provided with a dishful of plate mounting rod, in the interior hole path that is fixed in metal arc elbow body of described dish plate mounting rod bias, on dish plate mounting rod, be flexibly connected a dishful of plate, the diameter of dish plate equals the diameter of metal arc elbow body, and more than dish plate mounting rod is arranged on the endoporus center of metal arc elbow body, on dish plate, be positioned at dish plate mounting rod lower end integral type and be connected with a weight, described inner tube is teflon material, described metal arc elbow body outside is provided with flange, flange and anti-wear cover are by clamping bolt fixing and locking, between described flange and anti-wear cover, be lined with seal ring.
The beneficial effects of the utility model: the utility model is simple in structure, in metal arc elbow body, teflon material inner tube is set, completely cut off the corrosion of medium to metal arc elbow body, large leap ahead the working life of metal arc elbow body, and when inner tube damage, only need to change inner tube, reduce the unnecessary waste of material, in the interior hole path of metal arc elbow body, one-way valve is set, circulation medium can not hoarded in passage, reduce the corrosion of medium to passage, thereby increase the working life of metal arc elbow body.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the linkage structure schematic diagram of one-way valve and metal arc elbow.
Embodiment
A kind of channel bend as depicted in figs. 1 and 2, comprise metal arc elbow body, it should be noted that, in described metal arc elbow body 1, be provided with inner tube 3, the two ends of described metal arc elbow body 1 are welded with flange plate 2, at the inner wall even distribution of flange plate 2, have projection or C type groove, and the flange plate internal diameter of described two ends welding varies in size, the two end part of inner tube are flange 4 structures, and flange 4 inside are provided with steel wire support ring, metal arc elbow body outside is provided with an anti-abrasion cover, anti-abrasion cover comprises upper cover and lower cover, and upper cover and lower cover engaging, in metal arc elbow body, be provided with an one-way valve, one-way valve is eccentric-butterfly-valve, on metal arc elbow body, be provided with a dishful of plate mounting rod 5, in the interior hole path that is fixed in metal arc elbow body of described dish plate mounting rod 5 bias, on dish plate mounting rod 5, be flexibly connected a dishful of plate 6, the diameter of dish plate 6 equals the diameter of metal arc elbow body, and more than dish plate mounting rod 5 is arranged on the endoporus center of metal arc elbow body, on dish plate, be positioned at dish plate mounting rod lower end integral type and be connected with a weight, described inner tube is teflon material, described metal arc elbow body outside is provided with flange, flange and anti-wear cover are by clamping bolt fixing and locking, between described flange and anti-wear cover, be lined with seal ring.
The utility model is simple in structure, in metal arc elbow body, teflon material inner tube is set, completely cut off the corrosion of medium to metal arc elbow body, large leap ahead the working life of metal arc elbow body, and when inner tube damage, only need to change inner tube, reduce the unnecessary waste of material.
The above is only better embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model the scope of the claims therefore all changes or modifies, and is included in the utility model patent claim.
